In-session Settings

Once connected, the Yubikey device is transmitted from client to host. In the Parsec overlay, you can enable/disable the Yubikey for USB passthrough in the USB Devices menu.

Need to knows

  • During a Parsec session, if the Yubikey is enabled for USB passthrough, it will be unavailable on the client until you disable passthrough of the key in the Parsec overlay. This is because it is transmitting the entire device via USB over IP.
  • Yubikey support in Parsec has been validated for authentication but hasn’t been tested for advanced functionality like generating or storing certificates, firmware updates, etc.

 

Issues with passthrough

Client setting is stuck on 'Please wait' when turning on

It might be necessary on your system to install the Visual C++ Redistributable.
